How did limestone form.

Quicklime is formed by the process of calcination, in which limestones are heated to the dissociation temperature of the carbonates (402-898°C), and held there long enough to release carbon dioxide. Although the term "lime" in some cases is used to refer to pulverized limestone, it refers more correctly to quicklime (burned lime) and ...During the last ice age (100,000 years ago) sea level dropped, exposing the ancient coral reefs and sand bars which became fossilized over time to form the rock that makes up the island chain today. The two dominate rock formations in the Keys are Key Largo Limestone and Miami Oolite.Oolitic limestone forms in warm, shallow marine environments, such as lagoons and tidal flats, where the water is rich in calcium carbonate. The rock gets its name from the presence of small, spherical particles called ooids, which are formed through a process called ooid genesis. Ooid genesis occurs when tiny grains or fragments, such as sand ...
